i think they don't even have to do it ... last time when i missed a train, the lady behind the counter told me they didnt give certificates anymore (for employers to know you werent lying) because
everybody has a smartphone
and i was like
well yes i do but it doesnt have a sim-card in it and even if it did i couldnt afford a belgian telcom sub so ?
well yes sir, but ..
my point : everyone carrries the chip around
voluntarily, i just google the opening hours of the local store and google told me how much time people spend INthere approx ... which means they locate it , you're wearing the chip
RIGHT NOW
@ rudyardcatling Some stores have put micro-chips in the tags that are on their clothing. Items that are purchased are tracked.
